    Shoulder Sprain a Sprain Is a Stretch And/Or Tear of a Ligament, a Strong Band of Connective Tissue That Connect the End of One Bone with Another

    INDUSTRYADVANTAGE THERAPY UPDATE April 2016 A Courtesy Publication for the Monett area HR/Safety Community Sprains & Strains: What’s the difference? Does seeing the term “shoulder injury” at a glance make you cringe? In the work comp world, shoulder injuries can turn into costly claims involving surgery and long-term rehabilitation. Often times, shoulder injuries begin as sprains or strains and can be treated with conservative, non-operative treatment. In this month’s Industry Update, we’ll review sprains and strains as well as other factors that can contribute to shoulder injuries in the workplace. Shoulder Sprain A sprain is a stretch and/or tear of a ligament, a strong band of connective tissue that connect the end of one bone with another. In the shoulder complex, common sprains involve the supporting ligaments of the joint between the end of the collar bone and the shoulder blade - the acromioclavicular (AC) joint. Shoulder sprains can occur during repetitive reaching or lifting activities, or with falls onto the shoulder. Treatment for mild sprains includes RICE (Rest, Ice, Compression, Elevation) and exercises to improve muscle balance, preserve joint mobility, and provide support for ligaments. Shoulder Strain A strain is an injury to a muscle and/or tendons. Tendons are fibrous cords of tissue that attach muscles to the bone. Typical symptoms of a strain include pain, muscle spasm, muscle weakness, swelling, inflammation, and cramping. Strains are common when a pushed, pulled, or lifted object suddenly gives way. They can also be wear-and- tear injuries or a result from reaching out during a fall.
  • Wrist Fracture – Advice Following Removal of Your Cast

    Wrist Fracture – Advice Following Removal of Your Cast

    Wrist Fracture – advice following removal of your cast A plaster cast usually prevents a fracture from moving, but allows your fingers to move. The cast also reduces pain. What to expect It usually takes four to six weeks for new bone to form to heal your fracture. When the cast is removed most people find that their wrist is stiff, weak and uncomfortable to start with. It may also be prone to swelling and the skin dry or flaky, this is quite normal. It is normal to get some pain after your fracture. If you need painkillers you should take them as prescribed as this will allow you to do your exercises and use your wrist for light activities. You can ask a Pharmacist about over the counter painkillers. If your pain is severe, continuous or excessive you should contact your GP. The new bone gradually matures and becomes stronger over the next few months. It is likely to be tender and may hurt if you bang it. The muscles will be weak initially, but they should gradually build up as you start to use your hand and wrist. When can I start to use my hand and wrist? It is important to try and use your hand and wrist as normally as possible. Start with light activities like fastening buttons, washing your face, eating, turning the pages of books over etc. Build up as pain allows. Avoid lifting a kettle for 4 weeks If I have been given a Wrist splint You may have been given a wrist splint to wear.

O’Connor, UK Philippe Peetrons, Belgium Monique Reijnierse, The Netherlands Philipp Remplik, Germany Enzo Silvestri, Italy Elbow Note The systematic scanning technique described below is only theoretical, considering the fact that the examination of the elbow is, for the most, focused to one quadrant only of the joint based on clinical findings. 1 ANTERIOR ELBOW For examination of the anterior elbow, the patient is seated facing the examiner with the elbow in an extension position over the table. The patient is asked to extend the elbow and supinate the fore- arm. A slight bending of the patient’s body toward the examined side makes full supination and as- sessment of the anterior compartment easier. Full elbow extension can be obtained by placing a pillow under the joint. Transverse US images are first obtained by sweeping the probe from approximately 5cm above to 5cm below the trochlea-ulna joint, a Pr perpendicular to the humeral shaft. Cranial US images of the supracondylar region reveal the superficial biceps and the deep brachialis mu- Br scles. Alongside and medial to these muscles, follow the brachial artery and the median nerve: * the nerve lies medially to the artery. * Legend: a, brachial artery; arrow, median nerve; arrowheads, distal biceps tendon; asterisks, articular cartilage of the Humerus humeral trochlea; Br, brachialis muscle; Pr, pronator muscle 2 distal biceps tendon: technique The distal biceps tendon is examined while keeping the patient’s forearm in maximal supination to bring the tendon insertion on the radial tuberosity into view.

We described the first case report in the literature who developed Complex Regional Pain Syndrome (CRPS type I) symptoms in his right shoulder and right hand within 15 days after open cardiac surgery and discussed shoulder-hand syndrome (CRPS type I) and frozen shoulder diagnosis along with the reasons of no report of CRPS type I in these patients. We also speculated whether frozen shoulder seen in postthoracotomy and postcardiac surgery patients might be CRPS type I in fact.

Downloaded from Annals of the Rheumatic Diseases, 1989; 48, 409-420 'Dialysis related arthropathy': a survey of 95 patients receiving chronic haemodialysis with special reference to 132 microglobulin related amyloidosis N P HURST,' R VAN DEN BERG,' A DISNEY,2 M ALCOCK,3 L ALBERTYN,3 M GREEN,' AND V PASCOE4 From the 'Rheumatology Unit, the 2Renal Unit, the 3Department of Radiology, and the 4Department of Pathology, The Queen Elizabeth Hospital, Woodville, South Australia SUMMARY Ninety five patients receiving chronic haemodialysis (CHD) were surveyed to determine the prevalence of rheumatic disease and, where possible, its aetiology. At least three distinct rheumatic syndromes were identified-a group of patients with a syndrome consisting of large and medium joint synovial swelling, restricted hips and shoulders, tenosynovitis, carpal tunnel syndrome, and bone cysts due to deposition of 132 microglobulin related amyloid (AMP2m); a second group with erosive azotaemic osteoarthropathy; and a third group with age related degenerative disease of small, large, and axial joints. The data presented suggest that in patients receiving CHD (a) the prevalence of AM2i2m deposition and the associated syndrome increases with duration of dialysis, but in patients who have been dialysed for more than 10 years the risk of developing AM2n2m is related to age; (b) AM2i2m deposition in subchondral cysts, but not synovium, causes joint destruction; also, AMp2m may be more prone to deposition in synovium of joints already damaged by other processes; (c) in the absence of synovial iron deposition synovial AM2n2m is not associated with an inflammatory infiltrate; (d) hyperparathyroidism and perhaps other factors such as synovial iron deposition are probably more important than AMgi2m as causes http://ard.bmj.com/ of peripheral joint degeneration and destructive spondyloarthropathy in patients receiving CHD.
  • Wrist Fracture

    Wrist Fracture

    Hand Conditions: WRIST FRACTURE A wrist fracture is a break in one or more of the bones in the wrist. The wrist is made up of the two bones in the forearm called the radius and the ulna. It also includes eight carpal bones. The carpal bones lie between the end of the forearm bones and the bases of the fi ngers. The most commonly fractured carpal bone is called the scaphoid or navicular bone. This fact sheet will focus on fractures of the carpal bones of the wrist. Causes A wrist fracture is caused by trauma to the bones in the wrist. Trauma may be caused by: • Falling on an outstretched arm • Direct blow to the wrist • Severe twist of the wrist Risk Factors Factors that increase your chance of developing a wrist fracture include: • Participating in contact sports, such as football or soccer • Participating in activities such as in-line skating, skateboarding, or bike riding • Participating in any activity which could cause you to fall on your outstretched hand • Violence or high-velocity trauma, such as an automobile accident Symptoms If you have any of these symptoms, do not assume they are due to a wrist fracture. Symptoms of a wrist fracture include. • Pain • Swelling and tenderness around the wrist • Bruising around the wrist • Limited range of wrist or thumb motion • Visible deformity in the wrist For more information visit us online at www.ptandme.com Hand Conditions: WRIST FRACTURE Diagnosis Your doctor will ask about your symptoms, physical activity, and how the injury occurred. The injured area will be examined.
